Hell March <3btw did they actually build a new engine for this or is it just another brushed up version of the C&C Gold engine (Seems very unlike EA to make a new engine when they can just keep using old shit over and over, but the water looked quite different then what I remembered from C&C3 heh)?

Nearly 60% of the Sage engine's code was rewritten for Red Alert 3. The revamped game engine is now called RNA. Most attention went to the water (Now with splash animation! Demolition, animations, respectively to keep RA3 true to RA2's light-hearted style. This goes for the Japanese faction too.
